' v-tumlication filed November ToaZZ whom it mag oonoemzl' H a v Be it known that l, AUs s'r P SoHnjrm-a citizen of the United States fl-ndjil resident 1 o-1;the village of MortonGrove, in the county of Cook and State of Illinois have invented certain new and useful lmprovements in an Auxiliary Attachment for Pneu matic Tires; andl do hereby;declare-that the following is a. full clear, and exact description of the same re'i erence beingdiad' to vthe'accompanying drawings, and to, the numerals of reference marked thereonywliich form a part of this-specification, V

This inventionrelates to an auxiliary 321i? tachment .;]':'or pneumatic tiresand particularly to a device which makes possible the useof parts of wornytire casings] l'jllhen a portion QfittllG casing becomes WVOID -so;tha.t it cannot berepaired,-it ;is thegeneral p rac tice to discard the same orto sell the same forthe srrap rubbertherein, no effort being made to utilize unworn partsof-the tire casing. This practice isof course a wasteful-one and itis an object ofthe present in V vention to provide means whereby unworn portions of. used tire casings may be readily utilized in the repair or iny-the protection of pneumatic, tires that arelin use on vehicle wheels.

It is alsocan object of thisinvention to.

provide means whereby portions ofrthe tire casing may be clamped over-1a pneumatlc tire. in position ona wheel to reinforce or repairthe same. a 1 I a a It is a, further object of this-invent on to provide a clamp which is 'adapted lrto coact with a wheel to removably secure a -reinforcing member on a, pneumatic tire. which is mounted on the wheel. p i a It is an important object of this invention to provide anattac'hment for vehicle wheels which permits of the utilization :of portions. of worn tire casings intheureiniorcement and repair of pneumatic'tires mounted on said wheels. i

Other and further important iobjects of,

this invention will'lbe apparent fromthe disclosures in the specification and the ac-- companying drawings.

The invention (in a preferred form) is illustrated in the drawings and hereinafter more fully described. .7

Said attaching means comprises plates 6 and L7 whlch have arcuate grooves Sio'rmed on the innerv sides off :their outer edges and which have hook portions 9: "integrally 1 formed alongithe inneredgies otsaid' arcua te grooves thereby-adapting the same to be provided withan integral transversefporbytheimproved attaching means- 0f thisv tion ll which extends between the spokes'of the wheel to the other side of the felloe 2 and is provided with recessed extensions 12' which are adapted to receive the ends of.

pins 13which extend outwardly from a reduced portion 14 formed on the inner end of the plate 7. Said pins 18 are held in adlv justed position relative to the recesses in the nut or other suitable tightening nut 16,

mounted on its outer end on the outside of the plate 6, said bolt preferably being prevented from rotation relativeto the plates by the engagement of a head 17 thereon with shrouds 18 which are integrally formed on the outside of the plate 7. It is thus appar ent that the clamping eii'ect of the plates 6 and ?:on the segment be varied. by tightening or loosening the wing nut or other tightening means 16.

A. resilient. connection between the attaching means and the felloe is afforded by a bolt 19 which extends through the transverse portion ll 0]": the plate 6 and which is provided at its inner end with a button 20'rotatably mounted thereon and in engagement with the inner side of the felloe 2. Engaged be tween said button 20 and the inner side of the transverse portion 11 is a helical springQl and the amount of compression exerted on' said spring may be varied by the adjustment of a nut 22 which is mounted on the bolt 19 on the outside of said transverse portion 11. By thefadjustment of said nut 22 it is of course possible to vary the pulling effect which is exerted on the segments 5 by the plates 6' and 7.

Means which are illustrated in Figured may be provided for the attachment of antis'kid devices to the plates 6 and 7, said means preferably comprising bifurcated bosses 28 which are adapted to' receive the inwardly turned ends of spring clips 24 to which antislrid'members 25 are attached. By this arrangement, the anti-skid devices may be quickly and conveniently secured incp'osition. around the segments 5.

' Figure 5 illustrates an arrangement whereby the attaching means of this invention may be used in connection with straight side tires or tires which are not provided with the ordinary clincher beads 10. This is affected by the provision of a plurality of inwardly extending teeth 26 which are formed alongthe edges of the plates-('3 and i and which are adaptedto project into the side walls of the reinforcing segments at the thickened portions 28 thereof.

The use and operation of the auxiliary attachment of this invention will be obvious from the foregoing; description and need only be generally described herein. When it is only desired to repair a portion of a tire casing, it is ordinarily sufllcient to use one of the attaching means,'. thereby clamping, a segment of tire casing of suitable length over the worn or damaged portion of the tire. in case the entire tire becomes worn, an arrangement similar to the oneillustrated in Figure 1 may be employed, it of course being understood that any number of attaching meansand reinforcin segments may be used to meet the particular needs of the tire which is to be reinforced; It will be apparent from theforegoing description that this invention provides a tires and bythe use of this invention the waste attendant upon the throwingaway of old tire casings. or the sale otthe same for scrap rubber is greatly minimized.

While the attaching means are preferably constructed of light metal such as an aluminum composition, it will of course be ap parent that any suitable material maybe used in the construction thereof and that variouschanges may be made and details of construction varied through a wide without departing from the principles of this invention, andit is therefore not purposed to limit the patent granted otherwise than necessitated by the prior art.

I claim as my invention Ea clamp for holding a'tire protective section, comprising a transverse member adap ed for spanning the felloe of a wheel, a clamping member integral therewith and having a hooked-shaped peripheryadapted for engaging the beadoi a tire and a second
